THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 321,720, dated July 7,1885.

Application filed February 24, 1885. (No model.)

T0 all whom it may concern,.-

Be it known that I, JOHN HARRIMAN, of Milwaukee, in the county ofMilwaukee, and

in the State of Wisconsin, have invented cerwhich latter is shown incross-section in both figures.

A is the axle, and Bis the thill-elip. O

are the lugs that receive the eye of the thillstrap between them.Eaehlug C has a downwardly-inclined projection or jaw, C', in front thatterminates in a screw-threaded pin, O2, and between these pins C2 andthe projections or jaws O/ the rubber cushion D is inserted and followedby a plate, E, the pins passing through the plate to take nuts a. Shortlianges E on the top and bottom of plate E hold the rubber cushion inplace,and it (the cushion) is concavcd to t about the lower frontportion of the eye F of the thill-strap F.

In using my device the eye of the thillstrap is first inserted betweenthe lugs C and The plate secured by the bolt b and nut b.

E, with the cushion D held between its flanges, is neXt passed onto pinsC2, and then the nuts a are screwed on and tightened until the cushionpresses sufficiently against the eye F to prevent rattling, and then asthe cushion wears it may be advanced by tightening the nuts as long asany ofthe cushion remains.

By my construction I not only provide a perfect anti-rattlcr, but alsorender the breaking of bolt b less liable, as the cushion will relievethe bolt of a great deal of the draft strain.

Having thus fully described myinvention, 4 5 what I claim as new, anddesire to secure by Letters Patent, is-

In a thill-coupling, the combination of the thill-strap F', having eyeF, thill-clip B, havinglugs C rigid therewith, said lugs terniinat- 5oing in jaws C, and screw-threaded pins C2 solid therewith, and arrangedat an angle to the line of projection of the lugs C, rubber cushion D,plate E, having short iianges E, and securing-nuts a, substantially asset forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee, and State of Wiscousin, in thepresence of two witnesses.
